ELT 21b
Soil Summary:
very deep, textures vary widely and soils are often stratified – very fine sandy loam to silty clay surfaces with very gravelly coarse sand to silty clay layers below, limy, no or little development, some high water tables on lower terraces; dominated by Cochise County, Northwestern Part soil survey units 48 (Hantz complex,Chihuahuan, 0 to 2 percent), 17 (Cascabel, Quiburi soils, and Riverwash, Chihuahuan, 0 to 5 percent slopes), and 40 (Gila-Glendale complex, Chihuahuan, 0 to 2 percent slopes). These units comprise 63%, 17% and 6% of the ELT, respectively
Geologic Materials:
river alluvium associated with active channel and Holocene terraces (Qyr), late Holocene river deposits (Qy2r, Qy3r), and late Holocene alluvium (Qy2) which comprise 73%, 15% and 11% of the LTA, respectively
Landforms:
coarsely dissected, weakly to moderately incised mainly on river terrace breaks; terraces themselves show little dissection
